Neurophysiologists told why a person seems to have shorter days with age

Neurophysiologists from Japan in the course of a study found out why the days seem to be shorter with age. As it turned out, the perception of time is influenced by the physiological characteristics of the human brain.

Researchers analyzed the behavior of neurons in the supra-marginal gyrus of the parietal lobe of the brain. In this place, subjective time is counted. Experts invited volunteers to participate in the experiment, who were first shown a gray circle 30 times in a row for a certain time, which was voiced in advance. The second part of the test consisted of the fact that this figure was shown without a report on the duration and asked to estimate independently how long it lasted. The result was determined using functional MRI.

As a result, it was found that during the first part of the study the circle was shown for a long time, in the second it seemed to the volunteers that it was shown less. Experts explained this discrepancy as follows: with a long and repeated attempt many times to track and estimate the display time, the neurons responsible for this quickly get tired. If we transfer the results of the test to the daily life of a person, then the nerve cells of the right supra-marginal gyrus count and evaluate the time regularly. At a young age, brain cells are able to function normally, correctly determining the gap. However, over time, it becomes more difficult, since life experience is superimposed and the supra-marginal gyrus quickly gets tired.
